You have a lunch appointment with your friend at 12:30 pm. Suppose that your friend will arrive at the meeting place between 12:20 pm and 12:40 pm depending on the traffic condition. You arrived at the meeting place at 12:25 pm and found that your friend is not there yet. What is the probability that you wait for your friend more than 10 minutes?

Your friend Kate is never on time and is regularly anywhere from 3 to 21 minutes late. Let X represent the length of time in minutes that Kate is late and assume it has a uniform distribution.(Note: Labelled diagrams and proper notation are required for all parts.) a) Draw the probability density of X. b) Find the probability that Kate will be no more than 10 minutes late. c) Find the probability that Kate will be between 15 and 20...

The Transportation Security Administration collects data on wait time at each of its airport security checkpoints. For flights departing from Terminal 3 at JFK Airport between 3:00 and 4:00 pm on Wednesday, the mean wait time is 12 minutes and the maximum wait time is 16 minutes. (Transportation Security Administration, summary statistics based on historical data collected between February 18, 2008, and March 17, 2008.) Assume that x, the wait time at the Terminal 3 checkpoint at JFK Airport for...
